Developed to meet the requirements of Super Speed USB applications, the new devices provide effective 1, 2 and 3 line pair protection (Tx +/-, Rx +/-, D +/-) and filtering. Proven for 10Gbps communications line protection, the filter’s system-level robustness exceeds the IEC 61000-4-2 level 4, suiting them for use with sensitive SoCs.
The solution also minimises reflections when compared to a discrete design. The integration of Nexperia’s TrEOS technology results in low clamping and high robustness. PCMFxUSB3BA/C extends Nexperia’s family of Common Mode Filters (PCMF devices), helping to optimise the choice between differential pass-band and common-mode rejection at signal fundamentals and higher harmonics.
Commented Stefan Seider, Product Manager, Nexperia: “Apart from their capability to reduce EMI, Common Mode Filters with ESD protection are also very popular for their efficiency in protecting sensitive transceivers: They add an impedance to the signal line pair, which is very small for differential signals but shows significant attenuation of common mode noise as well as single-ended transients such as ESD.”
The new PCMF filters are available in very low inductance, space-saving WLCSP packages. Devices are footprint-compatible with available ESD-only solutions for fast design changes.
